Martin Logan Motion 4 Glossy Black Compact Bookshelf Speaker - MO4BL
Audiophile Performance without an audiophile price
Inspired by the clarity and detail of our ultra-high-end electrostatic loudspeakers,
Motion 4 features an exquisite Folded Motion™ tweeter and powerful bass technology
in a compact and affordable package. Key to Motion 4’s performance is the lightning
fast response of the tweeter’s light-weight diaphragm combined with a large

achieve a smooth, refined sound with stunning dynamic range and jaw-dropping
clarity—certain to inspire envy in audiophiles and non-audiophiles alike.
